2 Latoya has 60 CDs in her collection.
• 40 are Pop
. 12 are Country
• 6 are Rock
• 2 are Jazz
.
If she randomly selects a CD from her collection, what is the probability that she will NOT select a Country CD?
60 cds - 12 country = 48 cds are not country.
probability of picking one that is not country = total of non country/ total cds
probability = 48/60 which reduces to 4/5

52%. If the restaurant expected 105 people for lunch, how
many would you expect to order the daily special?
O 100
O 52
O 51
O 55
If the restaurant expected 105 people for lunch, using the given probability, the number of those who would order the daily special is D. 55.
What is the probability?Probability is the likelihood or chance that an expected outcome will occur amid many possible results.
Probability gives a fractional value of the whole when it is not 100% certain (when the possibility is 1)or 100% uncertain (when the chance is zero).
Like ratios and proportions, probabilities are depicted using fractions, decimals, or percentages.
The probability of ordering the daily special = 52%
The expected number of lunchers = 105
The number of those expected to order the daily special = 55 (105 x 52%)
Thus, if 105 are expected to attend the lunch, the probable number that will order is Option D.

Step-by-step explanation:
According to the image description provided:
Term one starts with one dot. One is an odd number.
If you add two to an odd number, the sum would be another odd number. This is what's happening with the pattern.
For example:

Lucas has 2 chocolate bars more than Caidon. Together they have 30 chocolate bars. How
many chocolate bars does Lucas have? (hint: use only one variable)
Help me
Answer:
Lucas has 16 chocolate bars
Step-by-step explanation:
Let x = number of chocolate bars Lucas has
⇒ x - 2 = number of chocolate bars Caidon has
If they have 30 chocolate bars altogether then:
⇒ x + x - 2 = 30
⇒ 2x - 2 = 30
⇒ 2x = 32
⇒ x = 16
Therefore, Lucas has 16 chocolate bars (and Caidon has 14 chocolate bars).
Listing broker Bob gets a 6 .5% commission on a $280,000 sale . He pays 3% to the selling broker and splits his share evenly with the listing agent . How much does the listing agent receive?
Answer:
4900 to listing agent
Step-by-step explanation:
SO Bob gets 6.5 -3 = 3.5 % and then splits it ==>1.75% to Bob and to listing agent
1.75% = .0175
.0175 * 280000 = 4900
A rose garden is formed by joining a rectangle and a semicircle, as shown below. The rectangle is 29ft long and 18ft wide. If the gardener wants to build a fence around the garden, how many feet of fence are required? Use the value 3.14 for, and do not round your answer. Be sure to include the correct unit in your answer
Answer:
The area of the garden is
797
f
t
2

Explanation:
First, let's find the area of the rectangle.
We know that the area of a rectangle is the length times width, or
20
⋅
32
in this example:
20
⋅
32
=
640
So the area of the rectangle is
640
f
t

.
You may not know the area of a semicircle, but that's fine
−
we know the area of a circle, or
π
r
2
.
Since the area of a semicircle is half the area of a circle, we just do the area of the circle divided by
2
:
So the area of a semicircle is
π
r
2
2
.
The question asks for
π
to just be
3.14
, so instead the equation is
A
=
3.14
r
2

The picture gives the diameter of the circle.
To find the radius, or
r
, we divide the diameter by
2
:
20
2
=
10
Now we can solve for the area of the semicircle:
3.14

10
)

(

)

Now that we now the areas of the rectangle and semicircle, we can add them up to find the area of the rose garden:

Divide. 8,375 ÷ 45 number and remainder
Answer: 186 with a remainder of 5.
Method One:
See attached for my work, I used long divison.
Method Two:
We will use a calculator to find the value, then multiply the value (without the decimals) by the divisor. Lastly, we will subtract. This makes more sense with the work:
8,375 ÷ 45 = 186.11111111
186 * 45 = 8,370
8,375 - 8,370 = 5

Area is measured in square units. This means that if we divide the shape into squares that are equal in size and count them up, the area is the total number of squares. Square units are always one unit of length long and one unit of length wide. In the song, the unit of length we use is feet. So each square unit is one foot long and one foot wide, or one square foot. Since there are 72 of these units in total, we say the area is 72 square feet. Square units can use other units of length, like inches or miles. Make sure you know what unit of length you’re using.

C: Jason is incorrect because 7 + 4 = 11.
D: Jason is incorrect because the area is 28 square feet.
Answer:
B

Maths problem in simultaneous equations
Answer:
Question 6: The cost of a chocolate bar is $1.20 and the cost of a box of gum is $0.75
Question 7: There were 7 students
Step-by-step explanation:
Question 6:We will be using system of equations which a set of one or more equations involving a number of variables. The solutions to systems of equations are the variable mappings such that all component equations intersect.
Our Variables:
- chocolate bar which will be represent as b in the equation
- box of gum which will be represent as g in the equation
Forming the equations:
Sally -
bought 2 chocolate bars (b)
bought 1 box of gum (g)
to a total of $3.15
so 2b + 1g = $3.15
Evans -
bought 1 chocolate bars (b)
bought 2 box of gum (1)
to a total of $2.70
so 1b + 2g = $2.70
Solving using substation:
2b + 1g = $3.15 we want to isolate b to input into the other equation
1b + 2g = $2.70
2b + 1g = $3.15 subtract 1g from both sides, divided both sides by 2
2b / 2 + 1g - 1g = $3.15 - 1g / 2
b = $3.15 - 1g / 2
Now substation b into the second equation
1b + 2g = $2.70 becomes 1($3.15 - 1g / 2) + 2g = $2.70
simplify,
$3.15 + 3g / 2 = $2.70 isolate g
$3.15 + 3g / 2 x 2 = $2.70 x 2 multiply both sides by 2
$3.15 + 3g = $5.40 subtract $3.15, divided by 3 from both sides
$3.15 - $3.15 + 3g / 3 = $5.40 - $3.15 / 3
g = $5.40 - $3.15 / 3
g = $2.25 / 3
g = $0.75
Now plug in g to get b into any equation:
If Sally equation is used
2b + 1g = $3.15
2b + 1(0.75) = $3.15 → 2b + 0.75 = $3.15
2b + 0.75 - 0.75 = $3.15 - 0.75
2b = $2.40 → 2b / 2 = $2.40 / 2
b = $1.20
If Evans equation is used
1b + 2g = $2.70
1b + 2(0.75) = $2.70 → 1b + 1.50 = $2.70
1b + 1.50 - 1.50 = $2.70 - 1.50
1b / 1 = $1.20 / 1
b = $1.20
Question 7:
Our Variables:
- adult which will be represent as A in the equation
- student which will be represent as S in the equation
Forming the equations:
- sample size: group of 30
- Adult cost $5 (A)
- Student cost $2 (S)
- Five members are free
to a total cost is $104
so A + S = 30 - 5
this is how many of each variable from the total group and we subtract 5 as 5 members were free
so 5A + 2S = $104
Solving using substation:
A + S = 25 we want to isolate a to input into the other equation
5A + 2S = $104
a = 18
s =7

The angle of elevation to a nearby tree from a point on the ground is measured to be 74^{\circ} ∘ . How tall is the tree if the point on the ground is 54 feet from the tree? Round your answer to the nearest tenth of a foot if necessary.
The height of the tree whose angle of elevation is [tex]74^{0}[/tex] and 54 feet tall is 188 foot.
Height of the tree= 188 foot (rounding off nearest tenth)
What is angle of elevation?The angle of elevation in math is "the angle formed between the horizontal line and the line of sight when an observer looks upwards is known as an angle of elevation".
We know by trigonometric ratios,

if each polygon has 12 sides and each side length was 20 cm what is the area
Answer: approximately 4478.46096908264 square cm.
==========================================================
Explanation:
I'm assuming this is a regular 12-sided polygon
The area formula for regular polygons is
[tex]A = 0.25n*s^2*\cot(180/n)[/tex]
where in this case we have n = 12 sides and each side is of length s = 20
So,
[tex]A = 0.25n*s^2*\cot(180/n)\\\\A = 0.25*12*(20)^2*\cot(180/12)\\\\A = 0.25*12*(20)^2*\cot(15)\\\\A = 0.25*12*(20)^2*\frac{1}{\tan(15)}\\\\A \approx 4478.46096908264\\\\[/tex]
The area of this regular polygon is approximately 4478.46096908264 square cm.
Make sure your calculator is in degree mode when computing that value of cot(15) or 1/tan(15).

9n^2 = 16 + 9
9n^2 = 25
n^2 =25/9
n^2 =25/9
[tex]\sqrt{n^2} = \sqrt{\frac{25}{9} }[/tex]
n= 5/3 or 1.67
[tex]~~~~~~9n^2 -9 = 16\\\\\implies 9(n^2 -1) = 16\\\\\implies n^2 -1 = \dfrac{16}9\\\\\implies n^2 = \dfrac{16}{9}+1\\\\\implies n^2 = \dfrac{25}{9}\\\\\implies n=\pm\sqrt{\dfrac{25}{9}}\\\\\implies n= \pm\dfrac 53\\\\\implies n = \pm1.67[/tex]
Wayne uses 4 inches of ribbon for each bow he makes. How many bows can he make with 3 yards of ribbon?
Answer:
27
Step-by-step explanation:
1 yard is 3 feet, so 3 yards is 9 feet.
9 feet is 108 inches, so Wayne has 108 inches of ribbon to work with.
Divide 108 by 4, because Wayne needs 4 inches of ribbon to make 1 bow, and we get 27.
Hopefully, this helps with whatever you need to do!
